Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Our grid

TenneT manages the high-voltage grid in the Netherlands and large parts of Germany. TenneT transmits electricity at 110,000 volts (110 kV) and higher. With around 22,000 kilometres of high-voltage lines, we cross borders and connect countries.

Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

Transport services

TenneT transports electricity along the high-voltage grid from where it is produced to where it is consumed.

Business model

Virtually all of TenneT's activities are regulated. These activities are governed by relevant legislative and regulatory provisions in the Netherlands and Germany. Regulatory authorities, Autoriteit Consument & Markt (ACM) and Bundesnetzagentur (BNetzA) oversee TenneT's compliance with these provisions. TenneT's regulated activities are managed on country level by two operating segments TSO Netherlands and TSO Germany. 
We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Transmission services
TenneT builds and maintains the high-voltage grid that is used to transport large quantities of electricity in the Netherlands and in a large part of Germany. The high-voltage grid functions as the 'highway' of electricity transmission and connects to the lower voltage grids of DSOs and to certain large industry users. TenneT also builds and maintains several cross-border interconnectors with neighbouring countries.

System services
TenneT operates the high-voltage electricity system. Because electricity cannot be directly stored, the supply and demand must continuously be kept in balance. TenneT ensures this balance 24/7, 365 days a year.

Facilitating the energy market
TenneT's third task is to facilitate a smoothly functioning, liquid and stable electricity market and to support the large-scale transition to renewables. As one of the largest TSOs in Europe, we play a leading role in shaping this market. Taking up this role is important to fulfil our strategic objective to have a fully integrated NWE market, improved security of supply, efficient use of interconnector capacity and an integrated wholesale price for electricity. Market parties and consumers benefit from an integrated European electricity market.
